The ECM controls the cooling fan corresponding to the vehicle speed, engine coolant temperature, air con-
ditioner system pressure and air conditioner ON signal. The control system has 3-step control [HIGH/LOW/
OFF]. This system indirectly relates to diagnostic trouble code 28 (Overheat).
Operation
ON-BOARD DIAGNOSIS LOGIC
This diagnosis continuously monitors the engine coolant temperature.
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise.
When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction is
indicated.

CAUTION:
When a malfunction is indicated, be sure to replace the coolant following the procedure in the MA
section (ªChanging Engine Coolantº, ªENGINE MAINTENANCEº). Also, replace the engine oil.
a. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure
to use coolant with the proper mixture ratio. Refer to MA section (ªAnti-freeze Coolant Mixture
Ratioº, ªRECOMMENDED FLUIDS AND LUBRICANTSº).
b. After refilling coolant, run engine to ensure that no water-flow noise is emitted.

2. Check valve opening temperature and
maximum valve lift.
Valve opening temperature:
76.5ÉC (170ÉF) [standard]
Maximum valve lift:
More than 8 mm/90ÉC
(0.31 in/194ÉF)
3. Check if valve is closed at 5ÉC (9ÉF)

INSPECTION END
Perform FINAL CHECK by the following procedure after
repair is completed.
1. Warm up engine. Run the vehicle for at least 20 minutes. Pay
attention to engine coolant temperature gauge on the instru-
ment panel. If the reading shows an abnormally high
temperature, another part may be malfunctioning.
2. Stop vehicle and let engine idle. Check the intake and
exhaust systems for leaks by listening for noise or visually
inspecting the components.
3. Allow engine to cool and visually check for oil and coolant
leaks. Then, perform ªOVERALL FUNCTION CHECKº.
